mobile water laboratory Articles

Today’s need for laboratories crosses many industries in a variety of ways. This is driven by numerous factors, but most notably by regulatory compliance requirements and the need to increase the efficiency of operations. Whether the need is for a mining operation’s compliance covering storm water quality or an oil/gas company running geochemical operations on well fluids ...

Imagine that you’re a field technician for a public water provider. Your company is committed to supplying clean, safe drinking water to millions of people, so it has implemented a sophisticated water sampling program to ensure water is free of contaminants. LIMS and The Mobile Lab: Data at your fingertips Across this water company’s territory, ...

Soil surface photolysis can be a significant dissipation pathway for agrochemicals under field conditions, although it is assumed that such degradation ceases once the agrochemical is transported away from the surface following rainfall/irrigation and subsequent drainage of soil pore water. However, as both downward and upward water movement occurs under field conditions, relatively mobile ...

Introduction the Water Corporation was established under statute as a corporatized entity. The mission of the Water Corporation is to conduct a successful business providing quality water and wastewater services to customers to enhance their lifestyle and to support the future development of the State. Asset Monitoring Services was established within the Corporation to undertake data ...

Aerojet, a GenCorp Inc. company, is a major space and defense contractor specializing in missile and space propulsion. Since its founding in 1942, Aerojet has been widely recognized as a leading force in the development of crucial technology and products that have protected America from potential enemies. In recent years, Aerojet has also played a leadership role in the implementation of ...

CETCO Oilfield Services was selected to treat and discharge approximately 150,000 barrels of hydrostatic test water in Houston, Texas. The water was treated and discharged into a nearby stream under a National Pollutant Discharge Elimination System (NPDES) permit from the State of Texas. The permit also required that there be no discharge of floating solids or visible foam, no discharge of ...

Background The Global Petroleum Research Institute (GPRI) at Texas A&M University-College Station regularly conducts laboratory research studies on various oil and gas produced wastewaters with varying sample matrices. The GPRI tests samples at different shale and oil producing formations using a mobile laboratory, which houses a pilot-scale treatment system for identifying the ...

Whole effluent toxicity (WET) testing has evolved into a critical element of many National Pollutant Discharge Elimination System (NPDES) permits issued to both industrial and municipal dischargers. Over 6,500 dischargers to both fresh and salt waters are required to conduct toxicity tests to determine if their effluent might be potentially toxic to organisms in the receiving system. While ...

Global’s Cougar and Falcon ROV systems were mobilized to Hawaii to facilitate repairs on the 40” coldwater pipeline transition section in 500 feet of water off of Keahole Point on the island of Hawaii for the Natural Energy Laboratory of Hawaii Authority (NELHA). ...

Northern Ireland Water is the sole provider of water and sewerage services in Northern Ireland. It is a Government Owned Company (GoCo) established in April 2007 to serve approximately 795,000 domestic, agricultural, commercial and business properties connected to the public water supply and 660,000 properties connected to the public sewer system. Every day Northern Ireland Water (NI Water) ...

A two-dimensional numerical model predicting flow over a mobile bed has been developed. Governing equations consist of the shallow water equations and the Exner equation. The finite volume method on an unstructured triangular grid was deployed to discretize the governing equations. The local Riemann problem is solved by the Harten, Lax and van Leer–contact (HLLC) method in the interface of the ...

The use of mobile phones has been the target of a great controversy due to possible biological and behavioural effects. This research presents a preliminary evaluation, regarding the learning and stress levels in subjects of the species Rattus norvegicus, submitted to microwave radiation. The psychological analysis was based on laboratory tests using the aquatic maze (tank of Morris), to ...

This report presents the results of concrete mix batching and testing using glass aggregate produced by Minergy. Crushed glass aggregate from the Minergy Pilot Plant produced from Fox River sediments was used in the batching and testing. This glass aggregate was incorporated into an air entrained concrete mix with ¾” maximum nominal aggregate size that is typical of a concrete mix that is ...

In order to protect aquatic life, many acute and short-term chronic whole effluent toxicity (WET) tests have been employed for assessment of the toxicity of wastewater. Toxicity tests using biological responses to measure effects provide valuable information about the significance of chemical contamination. The response of an organism to contaminated effluents provides an integrated measure of ...

The thought of transferring established high performance liquid chromatography (HPLC) methods onto a another vendor’s LC, or a new platform like UHPLC/UPLC, may cause a bit of anxiety for those that may be unaware of how easy it can be. The reason that the topic of analytical method transfer induces so much angst is that for the transfer of an LC method to succeed, the method has to work as ...

How to decide which chromatography system pump is right for you Well, you’ve made it this far and I am guessing that you are coming back because I have provided some useful information to help you understand the differences and nuances of a binary versus ...

In the Southeast Asia region, arsenic contamination of groundwater has been reported in several countries and a large number of arsenic treatment units were installed in many regions. Microbial activity can greatly affect the mobilization of arsenic under anaerobic conditions when coupled with the oxidation of organic matter. In this study, a mathematical model was developed to predict the ...

Coastal groundwater has been implicated as a source of microbial pollution to recreational beaches. However, there is little work investigating the transport of fecal microbes through beach aquifers where waters of variable salinity are present. In this study, the potential for fecal indicator organisms enterococci (ENT) and F+ coliphage to be transported through marine beach aquifers was ...
